价值
A vector can be linked here with which you can select a sample position within the noise pattern. Of course color values can also be used. If the 2D Value option is enabled, only the vector’s first two components will be read out and therefore only a 2D version of the selected noise pattern will be used.
这里可以链接一个矢量，用它可以在噪声模式中选择一个样本位置。当然也可以使用颜色值。如果启用2D 值选项，则只读出矢量的前两个分量，因此只使用所选噪声模式的2D 版本。
时间
The calculation of the noise pattern is based primarily on the Seed value. If you want to add variation to the pattern during animation you can, for example, link a Time Node here. Multiplying the time can speed up the animation of the noise pattern as desired.
噪声模式的计算主要基于种子值。如果您想在动画过程中为模式添加变化，您可以，例如，在这里链接时间节点。乘以时间可以加快动画的噪音模式的期望。
刻度[-∞ . . + ∞]
This is the scaling factor for the noise pattern’s structure. The larger the value, the smaller and finer the pattern will be.
这是噪声模式结构的比例因子。值越大，图案就越小越好。
2 d 值
If this option is enabled, only the X and Y components of the Value input will be read out. This results in the noise pattern’s depth component being ignored.
如果启用此选项，则只会读出 Value 输入的 x 和 y 组件。这导致噪声图案的深度分量被忽略。
噪音类别
Here you can select from a list of available noise patterns. These structures are also used in identical form by the Noise Material Node and the standard material system’s Noise shader.
这里您可以从一个可用的噪声模式列表中进行选择。这些结构也被噪音材质节点和标准材质系统的噪音着色器以相同的形式使用。
八度音[0. . 20]
Use this setting to control the noise structure’s level of detail. Larger values will create correspondingly more variations in the pattern.
使用此设置来控制噪声结构的细节级别。更大的值相应地会在模式中产生更多的变化。
绝对值
By default, positive and negative values are ascertained when a pattern is calculated. This potion can be used to only use positive values, which will result in an inversion of previously negative regions within the structure.
默认情况下，在计算模式时确定正值和负值。这种药水只能用于正值，这将导致结构内以前负区域的反转。
Seed [-∞ . . + ∞]
This is the numeric value on which the pattern’s calculation is based. Modifying this value will modify the variation of the selected pattern type accordingly.
这是模式计算所基于的数值。修改此值将相应地修改所选模式类型的变化。
空白[0.1. . 10]
This setting is available for several Noise Types and controls the density of detail in the gaps between the fractals. Generally speaking, the density of information between the structures decreases with decreasing values.
此设置适用于多种噪音类型，并控制分形间隙中细节的密度。一般来说，结构之间的信息密度随着数值的减小而减小。
增益[0.1. . 4]
This setting can be used for several Noise Types to smooth the transition between brightness and the structure. Larger Gain values produce a correspondingly more blurred result with less detail.
此设置可用于几种噪声类型，以平滑亮度和结构之间的过渡。较大的增益值相应地产生较模糊的结果与较少的细节。
指数[0.1. . 5]
This value is available for the following Noise Types: Displaced Voronoi, Voronoi 1, Voronoi 2 and Voronoi 3 and primarily affects the contrast within the Voronoi structure.
该值适用于以下噪声类型: 错位 Voronoi、 Voronoi 1、 Voronoi 2和 Voronoi 3，主要影响 Voronoi 结构内的对比度。
